or Underlay, of which the following is aV full pressure ofthe impression'memberV ofi-thev press is concentrated over the engr-avedor plate-into order to do embossed'lines of the better work.

Frevious to my invefntionfsuch'- counters were produced by drawinga knife-tip along through the iiber-boardcloseto the lines and then digging up to a. suitable depth the portions of the fibre-board outside Vsuch cuttings.

In my new process' I accomplishthe result in two ways, the first consisting in coinpressing to a predetermined level the portions of the fibre-board or other yielding material which are outside of the lines, and my second method consisting in punching closely disposed lines of holes adjacent the printed lines, and then tearing up the portions of the material thus separated from the printed lines.

In the drawings forming part of this specification, Fig. l is an edge view of a presstable having thereon a counter, overlay or underlay produced by the preferred form of my process. the production of another form of my process. Fig. 3 is a face view of a counter produced by either process. Fig. 4 is a partially sectional View of a tool employed. Fig. 5 shows another tool. Fig. 6 shows another tool. Fig. 7 is a perspective view of a machine used in the process.

The reference numeral l designates th table of a well known form of intaglio press having dovetail ways 2 for receiving the lat-r eral edges of a metal plate or slider 3 upon which is cemented asheet of heavy fiber-` board or other suitable material 4. Upon the exposed surfaces of'this yielding material 4, in one form of my process, is pasted a sheet of cardboard 4, and upon this is produced the printed or embossed matter;l

Fig. 2 is a similar view ofV this beingdone inthe usual manner-while the lplate and yielding materialare in place upon the table-1.

The slider S'is then'reinoved from the press and laid upon the tableV 5 ofa machine much like a. sewingfmachin'e, but one having V'a small punch, as 6 in'Fig.v 4, substituted for the needle. The/ end of this punch 'iis Vadjuste-dto reach .through the cardboardv 4 if used and slightly into'the board 4;' and,the`l machinebeingv set into rapid motion'tocause the punch tobe correspondingly reciprocated, the slider is carefully guided about upon theable 5 to cause the' punch toform` continuous lines' of perforations close to but outside of thevprinted' or embossed lines on the cardboard 4') 'l The sectionsof the cardboardv o utsideof the lines severed by the perforationsare then detached from the' -b/oard'4, leavingfthe sec jtions bearing the'printed lines elevated'the thickness of the cardboard above the board 4. In case the sheet of yielding material 4 is suliiciently light in color, the cardboard 4 may be dispensed with and the printing or embossing applied directly to its surface. Gtherwise, the process remains as above described. i

Where the blank spaces are large, as between the printed matter andthe upper f' corners illustrated in Fig. 3, the fine punch 6 is removed from the plunger 7 and a broader one 8 substituted therefor. Then, the plunger 7 being adjusted to descend slightly farther than before, the slider 3 and its attached libre-board 4 is moved about beneath the rapidly reciprocating tooll I 8 until the latter has beaten and compressed n sufficient of the fibrefboard, as at 13, to render the printed or embossed sections of the counter relatively high enough for perfect work.

If desired, a chisel-edged tool 9 may be substituted for doing the work performed by the fine punch 6 as above described, although the latter is preferable because of its ability to round corners'and sharp curves, and to it into small spaces.

The counter, overlay or underlay having been thus prepared, its plate 3 is slid into the ways 2 of the press table l, a sheet of paper or cloth secured over it, and the printing yor embossing proceeded with in the usual manner.

prefer to have the Shanks 11 of the tools made tapering and a square shoulder 12 provided therefor in order to facilitate the ready exchange of the tools.

By this method of preparing the counter, overlay or underlay, not only is considerable time saved in comparison with the use of a knife, but the worlr is. performed more uniformly and perfectly and vwith less danger of injury tothe counter hy any accidental slipping of the knife.

What I claim as my invention is.:

l. The process of preparing a counter, overlay or underlay, which consists in providing the exposed surface, of a layer of yieldingmaterial with an impression of the matter to be printed or embossed, punching lines of closely disposed holes to a predetermined depth adjacent the printing or embossing, and then lowering the surface of said layer outside said lines.

2. The process o f preparing a counter, overlay or underlay, which consists in pasting a sheet of cardboard upon a layer of yielding material, providing the exposed surface of the cardboard with an impression of the matter to be printed or embossed, severing the cardboard adjacent the print- Ved or embossed matter, and then tearing away the sections of cardboard separated from the printed or embossed matter.

3. The process consisting in providing the exposed surface of a layer of yielding material with an impression of matter to be printed or embossed, punching` lines of closely disposed holes adjacent .said matter, and then removing to a suitable depth the sections of' said material outside said lines of holes.

4. The process of preparing a counter, overlay o r underlay, which consists in providing the exposed surface of a layer of yielding material with an impression of matter to be printed, cutting lines of closely disposed holes to a predetermined depth adjacent said printed matter, lowering the surface of the yielding layer outside of but near to said lines, and then compressing restricted areas in quick succession outside of said lowered sections of the yielding layer.

5. The process consisting in providing the exposed surface of yielding material with an impression of the matter to be printed or embossed, punching lines of closely Vdisposed holes into said material adjacent .said matter, tearing away the sections of said material outside said lines, and then compressing restricted areas in sections of vthe yielding material outside said lines.

In testimony that I claim the foregoing invention, I have hereunto set my hand this 25th day of January, 1924.
